Wahh, this is tremendously helpful!! I can't thank you enough! Oh, and I hope you don't mind me asking but do you have any tips for drawing clothes? That's an area that I'm desperately trying to improve on. Any advice would be appreciated. If I'm bothering you, feel free to ignore this comment
As for clothing, Sketch them over the body, and remember where the folds will go. Look at yourself in the mirror and you can see. Usually (but not always) folds are around the armpits, chest, elbows and knees. There will also be more folds in other places if the clothing is baggy.
This was good. I can't get enough of anatomy tutorials; I have the worst issues with body proportions and such. Also hands, feet, and legs. That's why I usually draw chibis since they're allowed to be disproportionate. lol
